I deleted something important for windows(10). And then I formated all disks. I reinstalled windows 10 and all drivers last version. Everything was looking okay. Until I play lol. Before from the format I could see 200 fps on the same graphic settings. Now my fps is 60. And I check cpu speed. Before the format it was 3.80ghz(normally max 2.20 but I mean turbo mode here). Now it is stable on 0.79 ghz. What can I do?
